Gee, dare I try again—neuromelanin can be seen in the nigras of the brain on the right but NOT the left “ta dah!”

“Central 7”=lesion of corticobulbars to 7 (in the

CNS)

“Peripheral 7”=lesion to CN 7

Think about where the lesion could be!

Could the state of theface be a hint as to the location?
